"THEODTORE'B. \vricbx, OF NEWARK.

Be it known that I, Tniconouull \Vmcok,

aciti /Lcn ofthe United States, and resident of'Newark, county of l lssexistateof New Jersey, have nvented ccrtarn new [and u'sce ful Improvemcnts in A ')parat-us, 'for the: lllan'ufaeture of Bottle-Caps, of which the i following is aspecification;

manufacture of bottle caps in accordance \vitha 'novcl process invented by me and ,(lis-, closed in my application ,Serial Number ,424,919, filed -A ')ri1' 3, 1908 Tn=car1fying out this process, the usual metallic cap is employed as a matrix and the material which is to form the filling o'f'the'ea'p and ultimately to make a good seal surface forthe top ofa hottle," this material, mixed 'with some a d-.,

hcsive substance, as described in my said application, is pressed by a the orphinger plex IINX'lJHHlCill operations, ()ne fea'tur'e of theopcration' of any novel machine is that of feeding 'the metallic capsselcctively -from ahopper in which they ale deposited so that caps whichare 'turned in one diretg tion as thc c exit from'f the hopperare passed.

I through the machine in ,a proper-position-to be filled,- xvhile reversed or inverted caps are rqcctd or castout of the machine before they reach the filling= point.

As one feature of the structure, I may mention a circular table or plat-en having openings orrperforations near itsHperi-Phery, ,for receivingthe substance which is to form:-

thepads or cushions ofthe caps;
